Definitions
- the present invention relates generally to a medical device. More particularly, the present invention is related to a water dissipation device for placement in a breathing circuit.
- a breathing circuit delivers medical gas to a patient under pressure in a prescribed volume and breathing rate.
- the medical gas is often humidified by a humidifier located at or near the ventilator or respirator.
- the optimum respiratory circuit delivers 100% RH medical gases@35 to 39 Degrees C. to the patient while reducing the amount of humidity and subsequent condensate delivered back to the ventilator through the expiratory limb. Therefore, the humidified gas has to travel through all or most of the tubing and has time to cool. Cooling of the gas leads to rainout or condensation in the breathing tube and collection of water within the breathing circuit.
- a heating wire provided along the length of the tube.
- the wire may be provided within the interior of the tubing or alternatively may be embedded along the interior of the tubing.
- the wire heats the humidified gas traveling through the tubing to prevent the gas from cooling, thus preventing the problem of water condensing out of the gas traveling through the breathing circuit.
- the manufacture of such heated wire respiratory circuits can be time consuming and costly.
- a water collection apparatus is typically placed in the expiratory limb of the respiratory circuit in front of the ventilator or respirator to collect and manually remove excessive condensation prior to the gases entering the ventilator or respirator. It is known that excessive condensate entering a ventilator or respirator from the expiratory limb of a respiratory circuit can harm the device.
- the water collection device is designed to trap the condensed water vapor in a removable container. When the container is removed, a valve can be actuated to create a gas tight seal for the breathing circuit.
- this type of water collection device has to be monitored and manually emptied, causing risk of patient or caregiver infection.
- the improved apparatus for removing or decreasing water vapor or condensate in a breathing circuit reduce or eliminate the need to heat the exhalation limb of the breathing tube and the need to use currently known water collection or other dissipation devices.
- an apparatus in some embodiments provides an improved water dissipation device for placement in a breathing circuit where said water dissipation device will eliminate the need to use a secondary water collection device or manually remove the water condensate and will instead allow for removal of water vapor from the circuit through osmosis.
- a water dissipation device for a breathing circuit including a housing having a cylindrical bottom container having a side wall. The side wall defines a top opening. A lid is mounted on the top opening. The housing defines an entry port and an exit port for coupling to a breathing circuit and defining a first flow path between said entry and exit port. A breathable medium is enclosed in said housing. The housing defines a second flow path from the entry port of the housing through the tubular breathable medium to exit the housing from at least one opening other than the exit port.
- a water dissipation device for a breathing circuit having a cylindrical caged body enclosing an annular breathable medium.
- a first end portion defines an entry port coupled to a first side of said caged body.
- a second end portion defines an exit port coupled to a second side of said caged body.
- the cylindrical caged body defines a first flow path between the entry port and the exit port.
- the cylindrical caged body defines a second flow path from the entry port through the annular breathable medium and the cylindrical caged housing.
- a water dissipation device for a breathing circuit having a housing having a cylindrical bottom container having a side wall defining a plurality of windows.
- a lid is mounted on the cylindrical bottom container.
- the housing defines an entry port and an exit port for coupling to a breathing circuit and defining a first flow path between said entry and exit ports.
- a breathable medium is enclosed in said housing and the housing defines a second flow path from the entry port of the housing through the tubular breathable medium to exit the housing from at least one of the plurality of windows.

- An embodiment in accordance with the present invention provides a water dissipation device to remove water vapor or condensate from a humidified medical gas traveling through a breathing circuit between a ventilator and a patient or the patient and the ventilator.
- the present invention includes a water dissipation device having a housing defining entry and exit ports for coupling to the breathing circuit and a breathable medium permeable to water vapor and impermeable to liquid water, viruses and bacteria enclosed within said housing.
- FIG. 1 is a schematic view illustrating a breathing circuit 10 including a water dissipation device 12 .
- the water dissipation device 12 is placed in the breathing circuit 10 between a ventilator 14 and a breathing tube 17 from a patient.
- the breathing circuit 10 is completed by a second breathing tube 16 extending between the patient and the ventilator.
- the breathing circuit 10 is a closed system wherein liquid water and/or gases are not able to enter or leave the breathing circuit, except for the release of water vapor. Therefore, the breathing circuit 10 is a closed system except with regard to the passage of water vapor.
- FIG. 2 is an exploded view illustrating the water dissipation device 12 according to a preferred embodiment of the invention.
- the water dissipation device 12 includes a housing 18 having a cylindrical bottom container 20 .
- the cylindrical bottom container 20 has a side wall 22 that defines a top opening 24 and a bottom surface 26 .
- a lid 28 mounted over the top opening 24 .
- the housing 18 defines an entry port 30 and an exit port 32 , and more specifically the lid 28 defines the entry port 30 and the exit port 32 .

- the tubular breathable medium 36 may be pleated to increase the surface area of the breathable medium within the housing 18 .
- the breathable medium 36 may also line at least a portion of an inside surface 38 of the side wall 22 .
- a “breathable medium” is formed of a material that is permeable to water vapor and impermeable to liquid water and gases other than water vapor.
- the breathable medium 36 allows water vapor to exit the water dissipation device while eliminating the need to open the water dissipation device to empty a reservoir of water and, therefore, allows the system to remain closed.
- FIG. 3 is a cross sectional view that further illustrates the embodiment of the water dissipation device illustrated in FIG. 2 .
- the housing 18 defines a first flow path 40 of humidified gas between the entry port 30 and the exit port 32 .
- the humidified gas travels into the water dissipation device 12 via the entry port 30 , through the housing 18 and exits the water dissipation device 12 via the exit port 32 .
- the first flow path 40 therefore generally corresponds to the main flow path through the water dissipation device along the breathing circuit.
- the housing also defines a second flow path 42 for water vapor that extends from the entry port 30 through the tubular breathable medium 36 to at least one opening defined by the housing, other than the exit port 32 .
- this at least one opening includes the water vapor vents 34 defined by the lid of the housing 18 .
- water vapor in the humidified gas may permeate through breathable medium 36 and exit through the water vapor vents 34 .
- liquid water and other gases cannot permeate the breathable medium 36 and exit through the water vapor vents 34 .
- the bottom surface 26 of the outer housing 18 defines an orifice 44 to connect the water dissipation device 12 to an input air source.
- the housing 18 therefore, defines a third flow path 46 from the orifice 44 through the water dissipation device 12 and out through the water vapor vents 34 .
- the third flow path 46 provides a route for air introduced by the auxiliary compressed dry air input source to blow condensation off of the breathable medium to reduce liquid water collecting in the water dissipation device, and increase the efficiency of the breathable permeable medium.
- the annular or tubular breathable medium 36 defines a central channel 37 within which the second flow path 42 may follow.
